STRUCT LJCA_GPIO_INFO(9)

💅 struct ljca_gpio_info(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ and specifically to this little cutie of a struct. it's called struct ljca_gpio_info, and its whole personality is: "i'm the gpio client device info, and i know things." that's the vibe. that's the whole assignment. 🫶

---

✨ NAME ✨

struct ljca_gpio_info — ljca gpio client device info 💖

like, literally the info for your ljca gpio client device. no cap. 👑

---

🎀 SYNOPSIS 🎀

struct ljca_gpio_info {
    unsigned int num;
    unsigned long valid_pin_map[BITS_TO_LONGS( LJCA_MAX_GPIO_NUM)];
};

that's her. that's the whole struct. two members, zero drama, iconic behavior. 🌸

---

🌈 MEMBERS 🌈

• num — the ljca gpio client device pin number, i.e. how many pins this gpio client device is serving up. it's an unsigned int, so no negative energy allowed, periodt. ✨
• valid_pin_map — the ljca gpio client device valid pin mapping 💅 it's an unsigned long array sized [BITS_TO_LONGS( LJCA_MAX_GPIO_NUM)], which is giving "bitmap era" and honestly? we love a bit-level baddie. it's where the valid pin mapping lives, so you know which pins are actually valid. very main character energy. 🦋

okay and last thing, the cute little sign-off: this one comes to you from the source ./include/linux/usb 🎀, dated October 2026 ⭐, and yes it's struct ljca_gpio_info(9) all the way down. mwah 💋 slay, bye! 🌈
